Fort Hood, Texas: According to KCENTV, the Texas Department of Public Safety filed documents in federal court on May 19, 2022 which revealed the motive behind the April 22, 2020 killing of 20-year-old Specialist Vanessa Guillen.
For over a month, Vanessa was reported as missing until her remains were eventually located encased in concrete approximately 20 miles easy of Fort Hood near the Leon River.
The day after her remains were located Specialist Aaron Robinson committed suicide. His girlfriend, Cecily Aguilar is the only person charged related to Vanessa's death. She has been indicted by a grand jury on 11 charges related to her role assisting with the dismemberment and disposal of Vanessa's remains.
"Guillen saw Robinson's cell phone lock screen, which contained a picture of Aguilar," the documents say. "He told her he was worried about getting in trouble for violating the Army's fraternization rules since Aguilar was still married to another soldier and he hit Guillen in the head with a hammer."
The document discloses further revelations made by Aguilar.
Robinson "would go into moods in which he would not be his normal self and would have a 'tic,'" according to Aguilar. She reportedly told a fellow inmate that Robinson had "snapped, that he had an image in his head. He saw himself [kill Vanessa] and wanted to do it."
After Vanessa had been killed, Aguilar became involved, reportedly assisting in moving her remains from a government-owned tote that Robinson had placed her body in because he "didn't want to do it."
Aguilar additionally purchased concrete on the Facebook Marketplace, dismembered, and burned Vanessa's body.
She had told investigators that she and Robinson were home the night that Vanessa went missing, but after her remains were found, she confessed.
